	abstract = "A minimal parameter tight binding molecular dynamics scheme is used to study Cu<SUB> <I>n</I> </SUB> clusters with <I>&#36;n&#92;le24&#36;</I> . We present results for relaxed configurations of different symmetries, binding energies, relative stabilities and HOMO-LUMO gap energies for these clusters. Detailed comparison for small clusters <I>n</I> = 3-9 with <I>ab initio</I> and available experimental results shows very good agreement. Even-odd alternation due to electron pairing and magic behaviour for Cu<SUB>2</SUB>, Cu<SUB>8</SUB>, Cu<SUB>18</SUB> and Cu<SUB>20</SUB> due to electronic shell closing are found. We found electronic effects, electronic shell closing and electron pairing in the HOMO dominates over the geometrical effect to determine the relative stability of copper clusters. The present results indicate that tight-binding molecular dynamics scheme can be relied on to provide a useful semiempirical scheme in modeling interactions in metallic systems.",
